Incident with Actions

Resolved - On July 8, 2025, between 14:20 UTC and 16:30 UTC, GitHub Actions service experienced degraded performance leading to delays in updates to Actions workflow runs including missing logs and delayed run status. During this period, 1.07% of Actions workflow runs experienced delayed updates, while 0.34% of runs completed, but showed as canceled in their status. The incident was caused by imbalanced load in our underlying service infrastructure. The issue was mitigated by scaling up our services and tuning resource thresholds. We are working to improve our resilience to load spikes, capacity planning to prevent similar issues, and are implementing more robust monitoring to reduce detection and mitigation time for similar incidents in the future.
Jul 8, 16:44 UTC

Update - We are seeing complete recovery for Actions. New jobs will run as normal. Some runs initiated during the incident will be left in a stuck state and will not complete.
Jul 8, 16:43 UTC

Update - We have scaled out our capacity and customers will begin to see timely updates.
Jul 8, 16:29 UTC

Update - Some customers are seeing delays in updates to their runs resulting in missing logs and delayed run status updates. We are investigating the cause of the issue.

Disruption with some GitHub services

Resolved - On July 7, 2025, between 21:14 UTC and 22:34 UTC, Copilot coding Agent was degraded and non-responsive to issue assignment. Impact was limited to internal GitHub staff because the feature flag gating a newly released feature was enabled on internal development setups and not in global GitHub production environments.

The incident was mitigated by disabling the feature flag for all users.

While our existing safeguards worked as intended—the feature flag allowed for immediate mitigation and the limited scope prevented broader impact—we are enhancing our monitoring to better detect issues that affect smaller user segments and reviewing our internal testing processes to identify similar edge cases before they reach production.
Jul 7, 22:34 UTC

Update - We are investigating reports of Copilot Coding Agent service degraded performance

Disruption with some GitHub services

Resolved - On July 7th, 2025, between 18:20 UTC and 22:10 UTC the Actions service was degraded for GitHub Larger Hosted and scale set runners. During this time window, 9% of GitHub Larger Hosted Runners and scale set jobs saw a delay of at least 5 minutes before being assigned to a runner. Impact was more apparent to customers that didn’t have pre-scaled runner pools or who infrequently queued jobs during the incident window. This was due to a change that unintentionally decreased the rate at which we notified our backend that new scale set runners were coming online, and was mitigated by reverting that change. To reduce the likelihood and impact time of a similar issue in the future, we are improving our detection of this failure mode so we catch it in earlier stages of development and rollout.
Jul 7, 22:22 UTC

Update - We are investigating reports of degraded performance for larger runners.

Disruption with some GitHub services

Resolved - On 7/3/2025, between 3:22 AM and 7:12 AM UTC, customers were prevented from SSO authorizing Personal Access Tokens and SSH keys via the GitHub UI. Approximately 1300 users were impacted.

A code change modified the content type of the response returned by the server, causing a lazily-loaded dropdown to fail to render, prohibiting the user from proceeding to authorize. No authorization systems were impacted during the incident, only the UI component. We mitigated the incident by reverting the code change that introduced the problem.

We are making improvements to our release process and test coverage to catch this class of error earlier in our deployment pipeline. Further, we are improving monitoring to reduce our time to detection and mitigation of issues like this one in the future.

Jul 3, 07:12 UTC

Update - The rollback has been deployed successfully on all environments. Customers should now be able to SSO authorize their Classic Personal Access Tokens and SSH keys on their GitHub organizations.
Jul 3, 07:11 UTC

Update - The root cause for the rendering bug that prevented customers from SSO authorizing Personal Access Tokens and SSH keys has started rolling out. We are continuously monitoring this rollback.
Jul 3, 06:46 UTC

Update - We have identified the root cause for the rendering bug that prevented customers from SSO authorizing Personal Access Tokens and SSH keys.The changes that caused the issue are being rolled back.

Disruption with some GitHub services

Resolved - On July 2, 2025, between 1:35 AM UTC and 16:23 UTC, the GitHub Enterprise Importer (GEI) migration service experienced degraded performance and slower-than-normal migration queue processing times. This incident was triggered due to a migration including an abnormally large number of repositories, overwhelming the queue and slowing processing for all migrations.

We mitigated the incident by removing the problematic migrations from the queue. Service was restored to normal operation as the queue volume was reduced.

To ensure system stability, we have introduced additional concurrency controls that limit the number of queued repositories per organization migration, helping to prevent similar incidents in the future.
Jul 2, 16:23 UTC

Update - We're down to healthy level of queued migrations and the system is processing migrations at normal system concurrency levels.
Jul 2, 16:23 UTC

Update - Repository migrations are experiencing delayed processing times. Mitigation has been implemented and migration times are recovering.

Disruption with some GitHub services

Resolved - On July 2nd, 2025, between approximately 08:40 and 10:16 UTC, the Copilot service experienced degradation due to an infrastructure issue which impacted the Claude Sonnet 4 model, leading to a spike in errors. No other models were impacted.

The issue was mitigated by rebalancing load within our infrastructure. GitHub is working to further improve the resiliency of the service to prevent similar incidents in the future.
Jul 2, 10:16 UTC

Update - We are no longer experiencing degradation—Claude Sonnet 4 is once again available in Copilot Chat and across IDE integrations.

We will continue monitoring to ensure stability, but mitigation is complete.
Jul 2, 10:16 UTC

Update - We are experiencing degraded availability for the Claude Sonnet 4 model in Copilot Chat, VS Code and other Copilot products. This is due to an issue with an upstream model provider. We are working with them to resolve the issue. Other models are available and working as expected.
